Tweak an existing Github Jekyll plugin (Ruby)

I have created a Jekyll website with i18n support using the following plugin;

https://github.com/Anthony-Gaudino/jekyll-multiple-languages-plugin

Now I would like to add CMS support using the following plugin.

https://github.com/jekyll/jekyll-admin

But it will not support the non standard directory structure required by the i18n plugin out of the box, so it needs to be tweaked to work. I'm hoping that it should be fully customisable using the Ruby based HTTP API.

The solution can be delivered as a fork of the jekyll-admin plugin above or however you wish as long as evidence of it working is included by using the example site provided with the i18n plugin above.
Considering the flexibility of the plugin in question and documentation on how to use the API, I feel this should be a pretty quick mini project to knock out for someone with knowledge of the technology in question.
I have a technical background but not in Ruby, but hopefully enough to tweak going forward if I have a starting solution to work with.
